How it works: Nematodes seek slugs and water snails, they enter the body and start to develop from infective juveniles to adults. In doing so a pellet of bacteria is released that begins to multiply spreading through the host body. Infected slugs are noticeable by the swollen mantle on their back, this ruptures a few days later releasing thousands of nematodes that seek to infect further hosts.

Species controlled: Most slug species including Arion and Deroceras spp. and some snail species including those which are commonly found in nurseries.

When to use: Almost any time of year when soil temperatures are between 5 and 30°C. Soil moisture should not be a problem in commercial horticulture unless the area dries up completely.

Rates of use: Apply as a drench using conventional equipment, i.e sprayer, dilutor, watering can or through most irrigation equipment. In all cases remove any fine filters and ensure water temperature is between 5 and 15°C.
